Have you ever observed a near accident that made you cringe?

Several years ago I was in a large parking lot about to turn and two cars narrowly avoided hitting each other by a few inches. Neither hit their brakes or honked or anything. That scared me. Two other incidents before the evening was over. Saw a man turn onto a street from an intersection and run up over the curb and back down on the street, and saw something else on the way home. I just wanted to get home and stay. It was a full moon that night and thought that might have had something to do with it. Three incidents on one day was too much for me, had me spooked.
